The aim of the study was to determine the acute effects of single-whole-body vibration (WBV) on resting metabolic rate (RMR) and carbohydrate–lipid profile of blood in young, healthy women. The participants, in a randomised controlled crossover study, participated in two trials: WBV and a vibration simulation (placebo). The WBV was performed in the prone position and cycloidal-oscillatory vibration was used. The RMR measurement (calorimetry) was performed: before the WBV, during WBV, immediately after the completion of WBV, and 1 h after the completion of WBV. For biochemical analyses, venous blood was collected. During WBV, there was a significant increase in RMR compared to baseline. Immediately after and 1 h following the end of the WBV, RMR was close to baseline levels (p > 0.05). The increased energy expenditure resulted from the increased utilisation of carbohydrates and proteins during the vibration. In the placebo condition, there were no significant changes over time in the level of the studied indices during calorimetry. The WBV had no significant effects on the level of glucose in the blood. The applied vibration did not significantly affect the concentration of the analysed lipid indices, which were within the physiological norms for all measurements. Results indicate the need for further research to establish the physiological mechanisms underlying the observed effects of WBV on resting metabolic rate.

Purpose of the study was to examine relationship between distribution of healthy fitness zone standards of high school students and their type of housing or area of residence. Study sample consisted of 684 students (284 boys, 400 girls) from urban and rural areas of the region Presov in the eastern part of Slovakia. Physical fitness was assessed by four tests: back-saver sit and reach, shoulder stretch, curl-ups and 90° push-ups. Differences by place of residence and types of housing were examined by correspondence analysis of two-dimensional tables with computing Chi square value at significance level p < 0.05. Urban students performed higher level of flexibility, abdominal and upper strength and endurance than rural ones. Boys and girls living in a flat reached higher level of flexibility and abdominal strength/endurance however, they performed worse in upper strength and endurance than those living in a house. Slovak adolescents seem to have a healthier profile in abdominal muscular fitness and upper body flexibility than in lower body flexibility. The relationship between distribution of healthy fitness zone standards and residence area or housing type was revealed only in lower body flexibility, upper strength and endurance of urban and rural girls.

Background: The purpose of the study was to extend knowledge about the level of motor docility and selected cognitive and motor-cognitive abilities among secondary school students. Materials and Methods: A total of 43 children participated in the study. The Iowa Brace test was administered to assess the motor docility level. The motor-cognitive abilities were assessed by the Witty SEM system. The cognitive abilities were assessed by psychological tests that focused on attention, intellectual potential, and memory. The Mann-Whitney U test was used to determine the significance of gender differences in the level of motor docility and selected cognitive and motor-cognitive abilities of the students. The Kruskal-Wallis analysis of variance was used to determine the significance of differences between age groups. Results: The results indicate a low level of motor docility and cognitive abilities which may be caused by the quantity and quality of the acquired motor experience. Conclusion: Significant differences were observed in tests assessing the speed of thinking (BSQ) and in the mean reaction time in the speed of thinking test (BSRT), especially between the group with the lowest level of motor docility (0-4 points) and the group with a motor docility level at 10-12 points.

Purpose: Increasing energy intake and decreasing movement performance are among the greatest population issues of mankind. Risk elimination consists in returning to physically active way of life. The aim of the paper was to analyse the physical activity of female in selected secondary schools in the Presov district region, Slovakia, from the point of view of physical activity recommendations fulfilment.Methods: The research group consisted of 353 female students from 14 selected secondary schools in the Presov district region. The students were distributed in four groups according to age (15–18 years).Results: More than half of the studied females did not perform movement activity of medium or high intensity. The highest percentage of success rate in the criteria fulfilment was achieved by females of all age categories in walking 5 times per week for the minimum of 30 minutes (W 5 × 30). Only 44.3% of the students aged 15 years and up to 70.8% of those at the age of 18 met at least one criterion of the physical activity recommendations.Conclusions: As for physical activity recommendations fulfilment, the most successful criterion was performing physical activity regardless of its intensity. Physical activity recommendations seem to be very hard to implement in this age category, especially those concerning intense physical activity.

Background: Soccer players constantly experience rapidly changing situations that challenge them to receive and process stimuli, make fast and correct decisions, and perform actions at specific moments. The aim of the present study was to analyze age and experience-related differences in the level of brain speed, disjunctive reaction time, and reaction speed of soccer players. Methods: A total of 111 soccer players (x=12.414; s=1.921) divided by age and level of experience participated in the study. The diagnosis of brain speed and disjunctive reactivity was carried out with the BrainHQ Hawk Eye test and BrainHQ Agility test using the Witty Sem system. Reaction speed was diagnosed with the Fitro Agility Check test using the Fitro Agility system. The Mann-Whitney U test and the Kruskal-Wallis analysis of variance were used to determine the significance of age and experiencerelated differences in the level of brain speed, disjunctive reaction time, and reaction speed of the soccer players. Results and conclusion: Statistically significant differences (p<0.01) in favor of older age categories were observed between disjunctive reaction time and brain speed. Younger soccer players showed significantly lower levels of lower limb reaction speed in both directions of the sagittal plane than older players (p<0.01). Less experienced soccer players demonstrated significantly lower levels of lower limb reaction speed in both directions of the sagittal plane than more experienced counterparts and lower levels of brain speed and disjunctive reaction time (p<0.01).
